In this project, a device that independently manages the electricity consumer from several places and is completely safe was developed and constructed. The purpose of this development is safe management by the consumer of electricity in the domestic premises (staircases, corridors, etc.), even without replacing the old electrical wiring due to 5 V. Practical results – the simulated device was tested at a power consumption of 20 to 1000 W and showed a steady work of this design. The prototype of this device is successfully used at the Department of Electrical Engineering of the Mykolaiv National University. Novelty – control of electrical devices designed for power 220 V with the help of several switches, connected with each other by a wiring, calculated at 5 V.
